1/12 It has been confirmed that the #Taurus interception was done via “a non-secure line”. Below is my opinion of one way in which it *might* have been done, taking into account the situation and #Russia's previous history. Essentially it involves using #SS7 interception. 🧵

OST cannot be stopped. Here is a technique we tested internally 9 months ago: blocking EDR telemetry by leveraging the Windows Filtering Platform. Considered it so evil that we didn't publish it that time. It was pointless, now here it is by @netero_1010: github.com/netero1010/EDRSil…

Discovered and exploited an arbitrary file delete vulnerability that lead to SYSTEM level privileges. Thanks to the goat @filip_dragovic.

A certificate reseller bypassed the HTTP verification of the ACME cert protocol by using a remote code injection in ACME.sh to write their own When called out they are surprised Pikachu and say they didn’t know what an RCE was before this. 😬

I'd be pretty interested see how it fares with my new SDR Bluetooth sniffer and a bladeRF. Can it perform all-channel sniffing in real time? Benchmark with ice9-bluetooth -s -f /dev/urandom github.com/mikeryan/ice9-blu…

Great thread on the 300+ drones lost a day figure being generated as an approximation from UKR staff. They buried another lede here though! “Russian EW is…achieving real time interception and decryption of Ukr Motorola 256-bit encrypted…comms” RU stole and dumped radios!

It isn’t likely that they have some sort of Uber-leet exploit in the radio or the encryption itself - these radios aren’t likely hardened against an attacker dumping the radio contents, including any encryption keys. Reprogramming radios in the field is hard, so stolen keys last

Not for a hot minute tho right? Like part of fuzzing could be the AI can generate the test harness but that’s a far cry from current “coding ability” of AI I’ve seen so far. And web is such a hot mess of different stuff… Maybe in 2-3 years?

Generative AI aided fuzzing will lead to more binary and web exploits. Both defense and offense will benefit from this.
